and useful Improvements in Type-W'ritingf Machines, of which thefollowing is'a. specification.

My invention relates to retardingor speed regulating mechanism fortypewriting ma-.

chines and its principal object is to provide novel and improved meansof'connecting the retarding or regulating devices with the travelingelementpr carriage, enabling said devices to be rendered effectivewithout shock or' jar.

To the above and other ends my invention consists in the features ofconstruction, comparts hereinafter described and particularly pointedoutin the claims.

bodied in a No. 11 Remington typewriting machine and in connection withtabulating mechanism of the sort commonly found in said Remingtonmachine, but it is to be understood that said invention may be appliedto other styles of writing machines and tabulating mechanisms.

In the accompanying drawings, Figured is a fragmentary side elevationpartly in section of a No. 11 Remington typewritmg machine embodying myinvention, parts. of

r the machine being omitted and parts broken away. Fig. 2 is aperspective view of the novel retarder or regulator connecting devicesand associate parts, including the retarde-r proper and parts of thetraveling carriage. Fig. 3 is a vertical longitudinal sectional view ofthe retarder'or regulator device showing parts of the novel connectingdevices. Fig. 4 is a horizontal sectional view of the connectingdevices.

11s shown in Fig. 1, the main frame of the No. 11 Remington machinecomprises a base 1, posts 2 and a top plate 3 above which are fixedstationary grooved track-ways 1 cooperating through anti-friction balls5 with a carriage or truck 6 in which is mounted a platen 7. Pivoted inlugs 8 on the rear part of the carriage are arms 9 to which is secured afeed rack 10, said rack being norconnected with escapement wheels, thelatter cooperating with a dog controlled by'the printing keys to controlthe letter feed movements of the carriage as is well understood. Thecarriage is constantly urged leftward by a motor or spring drum 13connected by a strap 14 with an arm 15 secured by screws 16 to the rearof the carriage or truck 6 and shaped to extend upward, rearward anddownward behind the same as shown best at Fig. 2.

The tabulator mechanism comprises a toothed stop bar 17 supported onarms or brackets 18 fixed to andextending rearward from the carriage.Adjustably mounted on the stop bar are one or more column stops 19 withwhich are adapted to cooperate denominational stops 20 integral-with andat the forward upper ends of vertically disposed denomination levers 21'fulcrumed at 22 in a frame 28 detachably secured to the My invention isshown herein as em- .main frame. These levers are operative to projectthe stops 20 forward into the path of the c lumn stops by devicescomprising for each ever 21 a horizontal link 24 connected at its rcartothe lower end of said lever 21 and at its forward end to a bell crank 25having a fixed pivot 26, the forwardly extending arm of said bell crankbeing depressible by a key stem 27 provided at the top with a tabulatorkey 28 and slidable up and down in fixed guides 29. Each bell crank 25is provided with a restoring spring 30 for restoring the connected partsafter a tabulating operation. Each tabulator key 28 is operative notonly to project the associate denomination stop 20 but also to re leasethe carriage from the control of its cscapement' devices and permit itto be drawn-freely leftward for a tabulating run under the pull of thespring drum. The releasing devices comprise a bail or universal bar 31havingmpwardly extending ears or arms 32 fulcrume'd at 26, said bar 31being arranged behind the bell cranks 25 and operative by each of themto push rearward a link 38 connected at its rear to a crank arm 34 fixedto a rockshaft 35. tosaid rock shaft is an angular arm or member 36which is connected by an upwardly extending link 37 with a releasing orlevermember or frame of novel construction.

The releasing member comprlses a rearlink 37 is-connected, said arm 38being integralwith the body or cross portion 39 of said releasing memberand being bent rearward fromthe right end thereof, the left -end of saidbody-terminating is a rear- "the arm 38 and the ear 40 to provide afulcrum for the releasing member, said screws being supported inupwardly extendmg cars 44 of a- U-shaped bracket which further includesa body port-ion 45 connecting the cars 44, said body portion beingsecured in part to the top plate of the machine by a screw 46. It willbe understood that under the operation of a tabulator key 28 the link 37will be pulled down, thereby swinging the releasing member 38-41 on itsfulcrum and causing the shoe 41 to engage with the rack 10 and to liftit out of mesh with-the feed pinion 12 against the springs 11, so thatthe carriage will run leftward under the pull of the spring drum untilarrested by the'engagement of one of the column stops 19 with theprojected denominational stop 20. Whenthe key 28 is released a spring47, connected to the crank arm 34, assists to restore the releasingdevices to normal. inoperative position.

In order to regulate the speed of thecarriage when released as justdescribed for a tabulating run, retarding or regulating devices arepreferably provided. The regulating devices shown herein are thoseemployed in the No. 11 Remington typewriting machine but it is to beunderstood that regulating or retarding devices of any other suitablecharacter may-be employed. Said devices, as herein shown, are mountedin-a box or container comprising a cylindrical body portion 48 and anupwardly extending stem 49, said stem being threaded at its upper endand screwed into a supporting plate 3 fixedto the top plate, thusrigidly securing the container 48, 49 to the top plate.

As shown in Fig.3 the box or body portion 48 contains suitable material50, such as a mixture of small balls and graphlte, with whichcotiperates a rotating element or stirrer 51 fixed to the lower eno ofan upright shaft 52 which bears in the stem 49, and is shouldered so asnot to drop down out of place. I

The novel connecting devices for connecting the retarder or regulator-tothe carriage or traveling element comprise an engageable or clutchmember or device 53 secured by a set screw 54 to the reduced upper endof the shaft 52, said clutch member as shown in Fig. 3 being arranged inadepres- At its upper face the clutch member 53 is provided with one ormore engaging devices or teeth 56, two of these teeth being preferablyprovided and arranged diametrically opposite each other (Fig.-

As shown clearly in Fig. 2 these teeth are provided with vertical orworking faces which are adapted to cooperate with corresponding workingfaces on similar clutch teeth or engaging devices 57 formed on acoiiperating engageable or clutch member or device 58 which issli'dablymounted on the reduced upper end of the shaft 52. The member 58 isnormally separated from the clutch member 53 but is adapted to be sliddown to cause engagement between the clutch teeth or devices 56' and 57by devices comprising a spring arm 59 provided. at its forward end withforks or bifurcations 60 which have inwardly bent ends that engage witha circumferential so I groove or depression 61 formed at the lowerportion of the clutch member 58. The arm 59 extends rearward and is bentback on itself to provide a tongue 62, the rear portion of the arm andthe tongue being secured to the bracket body 45 by a shouldered screw63. This shouldered screw serves not only to secure the spring arm inplace on the bracket 45 but also assists the screw 46 to secure saidbracket to the top plate. Further thescrew 63 may serve as a regulatingdevice for regulating the: tension or spring and also the position ofthe arm 59. By turning the screw in or out the arm 59 may be raised andlowered and the tension or lift that it exerts is also varied. The holein'the body 7 of the arm through which the shoulderedportion of. thescrew 63 passes, is'larger diameter than said shouldered portion so thatthe arm 59 may move freely up and down lengthwise of said shoulderedportion. The shoulder on the screw confines the tongue 62 between it andthe top plate, the

hole in'said tongue being larger than and,

coiiperating with the. reduced end portion of said screw, said holehowever being smaller than the upper portion of the screw above theshoulder thereon. The arm 59 is depressible to lower the clutch member58 into engagement with the clutch member 53 by an arm or extension 64which is integral with and extends rearwardly from the body 39 of thereleasing member, said arm 64 overlying said arm 59 and having adownwardly bent end 65 which contacts with and forces down the arm '59when the releasing member is operated, overcoming the inherent tensionof said arm '59 and forcing the clutch member 58 into operative engagement wit-h the clutch member 53.

The clutch member 58 is constantly con-- nected with the carriagebydevices as now to be described so that the engagement of the twoclutch members efiects a connection between the carriage and theretarder or regulator. Said devices comprise generally a, yielding andelastic connection from the carriage to the clutch member 58 and morespecifically include a spring mounted cord, strap or band which issecured at its ends to the carriage and between us ends runs over apulley device or devices of which there are or may be two. One of thesepulley devices is preferably integral with the clutch member 58, beingformed by providing a circumferential groove or depression (36 at theupperpart of said member and above the groove 61. The other pulleymember (57 is mounted on a screw pivot 68 which rises .t'rom the topplate at theleft of the pulley,

and clutch member 58 and slightly to the rear of its axis, although itis obvious that if desirable the member (57 may be movably mounted onthe support or arm 59. The pulley (57 is provided with a circumferentialgroove 69 in a horizontal plane slightly lower than that of the groove66. The connecting member or cord 70 .may be of any suitable materialand is secured at its left end to a post or screw pin 71 depending fromthe left-hand bracket or arm 18. The right-hand end of said cord isconnected to a coiled draw spring 72 at the left-hand end of said drawspring the right-I iand end of said draw spring being hookedaround apost or screw pin 73 which depends from the arm or bracket 15 and isrigid thereon. The cord and spring 72 are arranged under the strap 14:.As appears cl .arly from l igs. 2 and at the cord wire or chain passesfrom the spring inward or toward the left and at the front of the member58, engaging with the groove 66 therein, thence passing around the backof said member 538 andthcn diagonally torwardaroinid the member (37,engaging in the, groove (59 therein and thence diagonally :torward againunder the other d agonal portion and over the forward side of the groove(31, not, however. contacting with the biiurcatcd portions b0 which arebehind the cord. By providing two pulleys as described .the cord turns'l'rcely and.

without contacting or rubbing against itself a so as to createunnecessary friction.

It will be observed that by myv present invei'itionl provide simplifiedand improved devices iior connecting the retarding or speed regulatingmechai'iisni' with thetrayeh lug element. or carriage: that saidmechanism includes flexible and elastic devices enabling the effectiveconnection between the carriage and the retardingmechan'ism to bebrought about.si'noothly and easily and without perceptible shock orjar; that the elas ic connecting devices arecombined with means orautomatically rendering them operative and inoperative to connect theietarding mechanism or devices with the carriage; that said means in thepresent instance includes tabulat-ing mechanism; thatthe flexibledevices in the present in stance comprise a cord or strap which issecured at its ends to the carriage; and is connected to a spring whichmaintains said cord under tension and renders the connection an elasticand resilient one thatthe elastic connection maintains a constantconnection between the carriage and one of a pair of clutch orengageable members, the

v other of which is constantly connected to the retarding devices; andthat one of these clutch members or devices is spring mounted by meansof a flexible arm or device controlled by a pivoted member or framewhich is automatically operative to release the carriage and render saidclutch devices etlfective one on the other.

Itwill be understood that various changes may be made without departingfrom the spirit and scope of my invention.
